Description

Utility class to extract free variables from data which has variables.

Documentation

class HasFreeVars a where Source #

Minimal complete definition

freeVarsOf

Methods

freeVarsOf :: a -> VarSet Source #

isClosed :: a -> Bool Source #

Something is closed if it has no free variables. This function may be replaced with a more efficient implementation.

elemFreeVars :: Var a -> a -> Bool Source #

Check if a variable is free in the given value. This function may be replaced with a more efficient implementation.

notElemFreeVars :: Var a -> a -> Bool Source #

Check if a variable is not free in the given value. This function may be replaced with a more efficient implementation.

subsetFreeVars :: VarSet -> a -> Bool Source #

Check if all variables in a set are free in the given value. This function may be replaced with a more efficient implementation.

disjointFreeVars :: VarSet -> a -> Bool Source #

Check if no variables in a set are free in the given value. This function may be replaced with a more efficient implementation.
